You just multiply these two numbers. It's 5200J, or 5.2kJ
Explanation:
Given that,
Two particles, an electron and a proton, are initially at rest in a uniform electric field of magnitude 570 N/C.
We need to find their speeds after 47.6 ns.
For electron,
The electric force is given by :
Let a be the acceleration of the electron. So,
F = ma
m is mass of electron
Let v be the final velocity of the electron. So,
v = u +at
u = 0 (at rest)
So,
For proton,
Acceleration,
Now final velocity of the proton is given by :
Hence, this is the required solution.
The correct answer is amplitude
The banking angle of the curved part of the speedway is determined as 32⁰.
<h3>
Banking angle of the curved road</h3>
The banking angle of the curved part of the speedway is calculated as follows;
V(max) = √(rg tanθ)
where;
- r is radius of the path
- g is acceleration due to gravity
V² = rg tanθ
tanθ = V²/rg
tanθ = (34²)/(190 x 9.8)
tanθ = 0.62
θ = arc tan(0.62)
θ = 31.8
θ ≈ 32⁰

Answer:
the atom number
Explanation:
atoms are determend by the numbers of protons in their core, as the number of protons determines what type of element the atom will be (noble gasses, Alkali Metals, Other Metals) and the atom number involves both protons and neutrons
